Load test wait times.

Are you shooting the ladder for pressure or accuracy? if accuracy you could skip to .4 or even .6 to save time, components and cooling time. just a thought.
Well, neither at this time, only speed.
From what I was told by a guy at a local reloading shop, (a professional competitor), he said to run through the loads to get the speeds to find the nodes first, then "Prove them" for accuracy and then fine tune them from there.
